function alphabet(count) { return Array.from({ length: count }, (_, i) => String.fromCharCode(97 + i)); }

Input & expected output

5

[
  "a",
  "b",
  "c",
  "d",
  "e"
]

The edge case

0

[]

Know the limits

• The original produced all 26 letters as a constant; a count input makes it runnable here.

The function above is the implementation used by the lab. The lab validates JSON types and caps size before execution; include equivalent validation when accepting untrusted input in your application.

Keep exploring

• Clone an array — Create a new array without copying the objects inside it.
• Remove duplicate values — Keep the first occurrence of each value, in its original order.
• Flatten a nested array — Turn a nested array into one sequence of values.
